Had some time over the weekend to touch up some things, including some long standing UI bugs.

* Identified consumables shouldn't appear in the "???" unidentified tab now.
* The input bug where question marks keep appearing should be fixed.
* A fair number of powers and effects that could not cause critical hits now can, this mostly applies to end game stuff but does include early powers like Power Drive.
* Door Spikes are fixed – previously when they sealed a door they also reduced all incoming door damage to 1, even though the screen said otherwise. This is no longer the case.
* Lightspears still work. Had to double check that one.
* There were a couple of other fixes from work last weekend but they were in a notepad++ file and I lost them.
